New Stone Fish Reefs
A contractor uses a trackhoe with a clamshell bucket on a floating plant to install fish reefs for the U.S. Army Corps of Engineers Pittsburgh District by dropping R5 riprap stones into the Monongahela River near New Eagle, Pennsylvania, Nov. 17, 2023. The Pittsburgh District contracted the work to install 73 fish reefs between Monongahela River miles 21.3 and 33.5 from Victory Hills to Clairton, Pennsylvania. The stone fish reefs’ purpose is to mitigate habitat loss that will result from removing Elizabeth Locks and Dam, scheduled for the summer 2024. The project started at the end of October and is expected to be completed before the end of November. (U.S. Army Corps of Engineers Pittsburgh District photo by Michel Sauret)
